■ PSW Inverter Details
■ PSW Inverter Wiring Diagram
We offer 3 optional working modes for psw inverter (transfer time≤4ms):
01 Grid priority mode: When the grid and battery are connected to the inverter, grid will supply power to the loads directly after voltage being stabilized and charge batteries via inverter. When the grid is cut off, the battery will automatically continue to supply power via inverter.
02 Energy saving mode: If the power of the connected AC loads is lower than 5% of the inverter’s rated power, there will be no output from the inverter. Only the chip of inverter is working. The power consumption of the inverter is only 1~6W. The LCD shows the output voltage 0. If the power of the connected loads is over 5%, within 5S the inverter will automatically convert DC to AC to supply power for the loads . The LCD shows the output voltage.
03 Battery priority mode: When the grid and battery are connected to the inverter, battery will supply power to the loads first. When battery capacity is not enough, the grid will continue to supply power automatically.

A: Tell me your requirements, such as power, voltage, charging current, quantity, and whether there are other functional requirements. We will give you the most favorable ex factory price. PSW Inverter dc to ac factory direct sales, no middlemen earn price difference.
Q3: What type of inverters do you produce?
A: We produce various types of inverters: pure sine wave inverters, off-grid inverters, on/off grid inverters, solar hybrid inverters, single phase inverters, 3 phase inverters, low frequency inverters, high frequency inverters, etc. Don’t know which type of inverter to choose? Contact XINDUN now!
Q4: What\'s the difference between pure sine wave inverter and modified sine wave inverter?
A: Pure sine wave output inverter is just as good as the public power grid, even better. Low repaired rate, long lifespan, without harmonic pollution, enviromental-friendly and appliances protected.
Modified sine wave output inverter has a negative impact on appliances and can\'t load inductive load, such as air contition, refrigerator and etc. Certain motor control circuits don\'t like the modified wave.
Q5: How to solve the psw inverter dc to ac technical problem?
A: We will provide market and product training services, 24 hours after-service consultancy just for you and to make your problem to solveeasily.
